I purchased several airports and I just noticed the taxi lines for progressive and runways are missing for KDFW and KLAX. I made these purchases just two days ago. Also the taxi tarmac areas look very poor texture with no detail. I checked other forum posts regarding this problem and one was to put "dynamicShadow.pye" into the coutl/common folder by replacing the one already there. This did not work. I do have the add-on manager. I rebooted FSX several times but no results. I do have FSX settings at the highest for detail also. I also purchased KJFK and KLAS but the taxi lines are there. Only missing for KLAX and KDFW. What can I do to fix this problem?
Update: I came across a post about installing "Standalone Add-on Manager" located at the product home page where you purchase the airports. I installed it and it seemed to do the trick for KDFW and KLAX all the progressive lines and runway lines and numbers are there, also the great textures are back. I hope this helps with others who may have had the same issue.
